Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion , sinkholes , loss of biodiversity , or the contamination of soil , groundwater , and surface water by chemicals emitted from mining processes.
In this report, an assessment is made of the literature on metal flows and cycles in nature and in society, the way they are connected, and the potential impact related to them. The four areas of focus are 1) Local impacts of mining, 2) life cycle energy use, 3) non-metal sources, and 4) the need for a final sink.
Once a mine closes, mining facilities that occupy a small area of the disturbed land can either be salvaged or town down. [13] The main visual and aesthetic impacts of mining are the open pits and waste rock disposal areas. Open-pit mining disturbs larger areas than underground mining making the visual impacts much greater. [13]
Strip mining eliminates existing vegetation, destroys the genetic soil profile, displaces or destroys wildlife and habitat, alters current land uses, and to some extent permanently changes the general topography of the area mined. [9] Adverse impacts on geological features of human interest may occur in a coal strip mine.
Environmental Impact Assessment (EIA) is an integral component of planning, development, and management of various industrial activities. It is widely implemented in many national jurisdictions and industrial developments. [1] However, the application of EIA and related environmental management frameworks remains underdeveloped for deep-sea mining.
For example, a paper presented in 1991 at a major international conference on this subject was titled: "The Prediction of Acid Rock Drainage – Lessons from the Database". [2] Both AMD and ARD refer to low pH or acidic waters caused by the oxidation of sulfide minerals , though ARD is the more generic name.
Last year, the World Bank approved a $73 million grant to help the Congolese government study the dam’s environmental and social impact. The dam, known as Inga III, would produce an enormous amount of energy in a country where there is almost none. But environmental experts say mining companies and aluminum smelters would be the main ...
